To ail wfiowt 'it muy com um.'

Be it known that l, Wlnnznn llaman, a subject` oi" the. En'ipcrrn of Austria. residing at Gyr, Kingdom of l'lungrary` have invented certain new and useful lmprove ments in Apparatus for lilanufacturing Chocolate Sweetmeats and other Confectionery5 of which the followingr is a specification.

This invention relates to an improved apparatus for manufacturing chocolate sweet meats, such as chocolate creams` drops, etc., and particularly to manufactiu'ing molded chocolate goods either by improved apparatus adapted, to build up uniform chocolate shells on centers previously molded or by molding the chocolate shells in the improved apparatus7 which shells constitute containers to receive a suitable hllinpr either in pas'ty fornnas a cream, or -in liquid form.

The object of the invention is to provide an improved apparatus for making coni'ectionery oit' the class described arranged for continuons and automatic operation and ein hodying the elements constructed and arranged as more particularly defined in the appended claims.

The employment of this improved appa ratus renders it possible particularly to so regulate the temperature of the material and spray it on sure a uniform distribution of the material without the aid of air blasts." shaking tahles,`and the likep heretofore used in chocolate coating' apparatus and also to up in recessed molds shells of chocolate in desired shapes which may be filled with any desired material as a center.

In cases where sweets, filled chocolate and other confectionery flat in shape are to be manufactured, it is suiiicient to employ one sprayer which )rays the covringz material on to the goods rom above so that the spray descends in an approxin'iately vertical direction. In cases' however, where the molds or confectionery to be formed are high and provided with sloping or vertical sides of comparatively large dimensions, it' is desir able to employ one or several heated casings in which there are arranged a plurality of and consequently also Specification of Letters Patent.

spraying in different directions and in noninterferinglr paths. ln order to allow a layer which has already lawn deposited on the goods to partially harden. the confectionery, before being further treated by another spi-avianr apparatus, may he cmiveyed through a cooling' chandler.

ne form of carrying the invention into effect is shown hy wa; oi example in the ac cou'n'ianying drawings. which show the improved apparatus diagrammatically.

Figure 1 shows one Jrorm of the apparatus diagrammatically in elevation; Fig. 2 shows another form ol the apparatus in elevation showing also the arrangement ol' the spraying devices. conveyor. and mold boards adapted to he contained within a heating casing, all in diagrammatic form; Fig'. il is a plan section taken on line 3-3 of Fig. 2; and Fig. 4 is a detail sectional view of one of the mold hoard showingr the chocolate shells as huilt up in the recessed spaces of the mold board.

In the illustrated example Fig. l the up per part of each heated casini! consists of a double walled vessel u adapted to he heated hy steam circulated between the spaces of the double walls of vessel t and casing by means of the inlet and outlet pipes indicated by a throughout the several figures. These pipes s are included in any suitable steam or hot water heating system. The vesselra serves for receiving the sugar or chocolate mass to be sprayed. This receptacle a is adjoined hy a larger double Walled copper cylinder b which may likewise be heated by steam. Inside this copper cylinder l) there is arranged a sprayerr which on the one hand through the intermediary of a pipe d and a valve e communicates with the vessel o and on the other hand communicates through a pipe f provided with a valve g and a manometer I1. with a tank p, or other vessel containing compressed air. The c0pper cylinder b is provided with a door z having! a window l which door gives access to the interior of the cylinder b and the sprayer e, and which further allows of `watching the operation of the. apparatus within the casing.

The lower part of each cylinder b is traversed b v a chain conveyor la on which the foods to be treated are placed in a 'mold-box `m. The chain is set in motion h v suitable driving means not shown.

At the side of the li rst casing b there arranged a coolingv chamber n through which thc chain conveyor if travels. and in which a low temperature is maintained by cooling Mills il. i

Next to the cooling chamber n there is an ranged a second rasing,r i) which is also travcreed by` the chain conveyer t',' and the sprayer r: of which is arranged diilerently when compared with the sprayer provided in. the first boiler, so that it sprays the material on to the goods from a different dircction.

Any desired number of such heated cas-` ing's and sprayers pointing in different di Martinus may bc provided, the boilers alternating with cooling chambers. ln small inslallalions the confectionery may be sub- :"id to a repeated treatment also in the foimviug manner:---'l`he mold board is posed tor instance a second time through the saine spraying.r apparatus in a direction at right angles to the direction in which said mold board traversed this spraying appa ratos the first time.`

When thc apparatus is Working, the valve (f is so adjusted that the mass drops down uniformly from the vesscl'a until it reaches ,the sprayingvalre where itis finely sprayed by the com pressed air supplied by the pipe f', so that it ,is applied in the' form of a fine spra y to the niold or hollow chocolate article containing a lliquid-V or solid filling, and moved past the sl'irayer on the endless chain 1. 'By heating the cylinder Z) ithis rendered possibleto-ohtain a very fine spra,r which, if necessary, iniiy traverse a comparatively long course or distance without there being any tear of tlie spra ved chocolate or sugar mass rapidly solidifying. By suitably adjusting the tenii'ierature, the sprayed chocolate or sugar mass may be caused to run together to form a layer, but be prevented from flowing down thc sides of the mold or the support on which the confectionery is placed. If required said support containing the confec tionery on to which the material in question is to bc sprayed.r may be kept at a suitable temperature, When the spraying; has been effected in one of the casings Y, the goods are conveyed by the chain conveyer c through the cooling chamber n andl from there if necessary through a second casing similar to and for the same purpose as th one described, where the confectionery, it' desired, is subjected to another spray diiferently directed to the previous one.

In order to most efficiently cover a recessed mold. it is preferable to arrange several sprayers, in one or more heated casingrs, so that the chocolate or other material may be sprayed in the recessed mold from several different directions. An example of such an arrangement is shown diagrammatically in Figs. 2 and 3', in which the reference characters indicating,y parts corresponding to thc similar parts in Fig. ll are primed. ln the d rawings, four sprayers are shown arranged in one common` heating chamber, and the spraying devices direct the spray in noninterfering paths and at different angles. It will be seen from this arrangement that a mold board as m (Fig. Ll) having recessed spaces of any desired size or configuration may travel across the several spray paths and since-the sprays are directed at different angles receive on` all their sides t, vu, c, and y, a uniform layer. In other words, a` chocolate shell is built up in each recess which shell may be subsequently used as a. container for pasty or liquid. centers. Especiallyy where the latter kind of center is de sired1 the `formation of containers as outlined is of particular importance. The method heretofore used for forming chocolate covered confections involves the molding oi the center first and the application of the coating or containing shell serond. The present apparatus where the recessed molds are used reverses this method as the shell is first formed, and with the shell as a container one is not limited to the consistency of the center for the shell inasmuch as a liquid can be used it desired. Therefore, the present apparatus while not confined in its operation to the formation of chocolate containers, nevertheless, has peculiar advan- 100 tages in that such containers can be made iu a continuous and automatic manner. So

tar as known, this useof the apparatus is broadly new.
